摘要： PURPOSE: A thermal conductivity measuring apparatus of nano fluid using a transient hot-wire method is provided to accurately measure thermal conductivity because the errors due to tension and inclination of a hot wire are minimized by using first and second fixing units. CONSTITUTION: A thermal conductivity measuring apparatus(100) of nano fluid using a transient hot-wire method comprises a top plate(110), a bottom plate(120), a cylinder(130), a first fixing unit(150), a second fixing unit(160), and a hot wire(W). The top and bottom plates are separated from top and bottom and between the plates, the cylinder is installed. The first fixing unit is coupled to the top plate to be penetrated. The second fixing unit is installed on the top of a movable plate(140) and located in same vertical line with the first fixing unit. Both ends of the hot wire are fixed to the first and second fixing units.
